1042-1046 Powell St, San Francisco, CA 94108

The two-unit residential building at 1042-1046 Powell Street in Nob Hill, owned by Katherine L Wong, is a two-story flats and duplex structure built in 1900. The property has undergone several significant maintenance and improvement projects over recent years, with the most notable upgrades occurring in 2019, including an electrical panel upgrade throughout units and common areas, a 200A service upgrade, and a furnace replacement.

These improvements were triggered by a building complaint filed in August 2019 regarding unauthorized construction work that exposed foundation, plumbing, and electrical components, along with an earlier complaint from April 2019 concerning improper lead paint removal and general maintenance issues. The building's infrastructure has required ongoing attention, particularly related to sewer systems, with several incidents recorded between 2023-2024 involving sewage backup issues from the side sewer vent, including a noteworthy discharge incident in December 2024.

The property's exterior maintenance has been documented through various complaints and repairs, including sidewalk defects, missing sewer vent covers, and deck modifications to facilitate electrical work. The building's historical records show earlier maintenance work including re-roofing in 1994, sidewalk repair in 2004, and porch repairs under the name of Daniel Lee Wong. The property has experienced typical urban challenges such as illegal parking incidents and street cleanliness issues, as evidenced by multiple 311 calls between 2021-2025, though these are generally unrelated to the building's structural or maintenance concerns.
